, the work is moved by an endless traveling apron while undergoing pressure from a rotating cylinder cooperating with the ironingsurface of the bed, and it relates 'more particularly to an improvement in the variet of mangles in the class referred to in whic the articles to he mangled are caused to traverse the concave surface of the bed for the ironing purpose and the convex surface thereof for dryin The primary 0 ject of my improvement is to provide a construction of mangle oi the variety last referred to whereby the surfaces traversed by the work shall be greatly increased in length with the advantage of accordingly increasing the extent of subjection of the work to the ironing and drying 0 erations and whereby particularly the po ishing of the work shall be materially enhanced after ironing it by stretching it over the end or nose of the heated ironing-had in its course to the outer convex drying-surface of the latter.

in the accompanying drawings, Figure 1 is a longitudinal vertical section of my improve inangle in its preferred form; Fig. l a broken enlarged view in elevation of means for suspending the central apron-supportinmroller; Fig. 2, a view showing the gears or driving the movable parts in side elevation with the frame and other parts shown by dotted representation; Fig. 3, an enlarged view in elevation of a broken section of the frame carr ing an adjustable detail for yieldingl hol ing a roll against the steam-chest wit which it cooperates, and Fig. 4 a section-taken at the line at on Fig. 3 and viewed in the direction of the arrow.

A is the frame of the machine; one side of which is represented in Fig. l and the other corresponding side indicated in dotted lines in Fig. 2, the sides being connected by brace rods at a, extendin between them. BracketsB' are shown to be provided on the frame at the feed end of the machine for supports ing the hasket- (not shown) and bracket extensions C of the frame are ing from its opposite end. I

D and D are two steam-chests rigidly supported to extend between the frame sides at o t is chests meet along their u per edges, as represented at a: in Fig. 1, an whence they diverge curvedly to present concave upper and convex lower surfaces with rounded outer extremities or ed es forming noses I).

Gylinders E and %l', forming padded ironin -rollers which are not heated, are journeiled on, the frame to fit into the concave surfaces of the respective steam-chests,

shown projech posite sides of their vertical centers where V each of which extends around about one half the circumference of the cylinder with which it cooperates. For journaiing the cylinders I'jemplo at the op osite ends of each the means il' ustrated in igs. 3 and 4, involving the following-described construction. A rectangular plate a is provided near its lower end with a circular ope c, having a flange '0 forming a hub and a ording a hearing for an eccentric d on a shaft cl, made angular at one end, as shownat d, to ermit the application to it of an operatingandle (not shown) for turning the shaft to rotate the eccentric. The shaft passes through a yoke e near its lower end, having a cross-- piece e extending between its arms near their lower ends, the yoke-arms having concave bearings 6 formed in their upper ends for the ends of a pin passing transverselythrough the arms 0 another upper yoke g, inverted relative to the yoke e and having its arms confined between those of the lower. yoke, which are formed on their inner faces with guides, as shown, to permit the upper yoke to reci rocate vertically under the control of astifi coi ed spring h, which is fastened at its opposite ends, respectively, to the pin fiend cross-piece e. The yoke 5; contains an elonated slot g above itshrms and has a sleeve g orrned to project from the inner side of its upper end and form a roller-bearing containing in its outer end a chamber g for packing 11 to be lubricated through anhese bearings are provided on each si the frame in the ositions indicated 2 by bolting the pihte c thereto and screwmg 'a headed r slot g in t e upper yoke g which is confined laterally between guides the top of the frame. 7 As will be' understood from the foregoing ic, projecting from gin 'i into the frame through the description of the hearing, it may be bodily raised or lowered on its plate 0 by turning the shaft d to turn the eccentric d accordingly and that the yoke 9 may be raised relative to the yoke against the resistance of the spring h, which tends to hold it down with the pin f against its bearings The two bearings for the opposite ends of each ironing roll or cylinder employ one shaft (6, extending across the frame to engage the eccentrics of both bearings. The bearing construction thus described is the same as that set forth in my pending application for Letters Patent, Serial No. 221,692, filed August 22, 1904-.

An endless traveling apron F, guided by rollers suitably journaled in the frame, extends as follows: from a roller about the cyiinder E to the nose b of thesteam-chest D; thence about said nose I) over the convex surface of .(the chest D and about a roller m s ring-suspemled, as hereinafter described, t lence over the convex surface of the steamchest D and its nose I) about the cylinder E, from'which it: passes about a roller n and across a roller 0 about a gravity-roller 1), having its ends confined to be vertically movable iu guides q, thence over a roller 7" and under a roller 8 to the roller Z. The roller m, which its between the steanr-chest below their junction, is journaled at its ends in hangers, (indicated at tin Fig. 1 and Fig. l"",) and each hanger is connected with a spring 1?, fastened to an arm a oi a bell-crank lever G, which is fulcrumed on the frame at '2 -When the machine is not in operation, and

itis therefore desired. to remove the ironingcylinders out of engagement with the steamchests, the shafts d are turned to cause the eccentrics to raise the cylinders and support them in their raised positions, and the levers G are turned on their fulcrums w to slack the tension of the springs t and permit the roller m to drop below the position in which it is represented in Fig. l, with the effect of re dueing the endless apron F to a slack con.- dition.

Fig. 2 shows the gearing for driving the ironing-cylinder and the apron, and following the description. thereof:

The drive -shaft i, which carries a pinion 2 and turns in the direction of the arrow on Fig. 2, meshes with a gear on. a shaft 4, journalcd on the frame, this last-named gear meshing with a larger gear F; on a shaft 6, suitably jourualed in the frame end carrying; a pinion 7, which meshes with a gear Is on the cylinder i The pinion 3 also meshes with a gear 9, llli(, i,l1(?{(itl3, on a Sllii-ft it), suitably journaled on the fram and the gear i) meshes with a gear 11, like gear 5 on a shaft 12, suitablyjournalwl in d, frame, whichcarrics a pinion l3, meshing with a gear 14, like the gearS on the cylinder l By following the motion of the moving scenes members of the machine it will be seen that the work to be mangled when fed to the traveling apron i at t io point X in Fig. l is carried about the first cylinder E and ironed against the concave surface of the first steamchcst l), whence it is carried about the nose l; of the chest l) over the convex surface of the latter and about the roller m, whence it is moved over the convex surface of the second steam-chest D and about the nose 6 of the latter between its concave surface and the second cylinder E, from which the apron conveys it to the point of discharge at X. The gravity-roller 1) tends to maintain the desired taut condition of the apron in a wellknown manner.

It v be observed that in the progress of the wort; through the mangle it is first ironed on one side against the bed D, then stretched over the respective nose I), and thereby polished, that in its subsequent course over the convex surface of the two steaneehcsts D and D it is thoroughly dried and thereupon stretched over the nose I) of the chest D, and

thereby further polisl'icd, whereupon ironing it against the concave surface of the last named steamehest com )letes the ironing and polishing, and thus finishes the work preparatory to its discharge from the machine It will also be observed that the action of the cylinder E is topull the work and stretch it over the nose I) of the chest D andthat the action of the cylinder E is to pull and stretch the work over the nose I) of the ironing-bed D.

hat I claim as new, and desire to secure by Letters Patent, is-- 1. in a'mangle, the combination of a con- CSNU-OOIIYO) steam-chest terminating at its out-er edge a nose, a padded ironing-roller journaled to cooperate with the concave surface of said chest, and an apron. arranged to travel and feed the work initially over said roller and to pass thence immediately between the eoncave surface of said chest and the roller, thence over said nose and thence against the convex surface of said chest, whereby articles to be mangled may first be carried by the apron to be ironed against said concave surface, thereupon stretched over and polished against said nose and then dried by contact with said convex surface.

2. In a mangle, the combination of a concavo-couvex steam-chest terminating at its outer edge in a nose, a padded ilOl'liIig-IOllBl' journaled to cooperate with the concave sur face of said chest, means for raising and. low
